Importing the necessary libraries

Question 1

Define iterations, input signal and the filter type

Going forward in the wavelet transform

Returning to the original signal

Question 2

Define the input image, number of iterations and the filter type

Apply and plot wavelet transform

Visualize inverse transform and calculate the MSE diference with the original image

Question 3

Define the input image, number of iterations, filter type and noise and soft-threshold parameters

Add noise to the image and make a comparison between both original and noisy images

Apply the soft-thresholding on the wavelet coefficients and plot the results

Question 4

Define the input image, number of iterations and the parameters for compaction

Compact the image and compare the reconstructed image to the original one

Experiment compressing the image
